摘要: 本文以国产芳纶1414纤维和美国杜邦Kevlar49纤维为实验材料,通过红外光谱和粘度的检测并计算其聚合度,比较分子结构的差异。同时通过超声波对蒸馏水中和自配海水中的芳纶纤维进行处理,经扫描电镜(SEM)和力学性能测试,发现经过超声波处理后的纤维表明,纤维表面出现了裂缝,呈分丝帚化及细纤维化现象,存在着微细原纤维,强力弱环增加,纤维断裂强度与断裂伸长率均下降,本文利用分子运动理论对纤维的力学损失进行分析。
Abstract: Aramid 1414 fibers made in China and Kevlar49 fibers made in the USA as experimental materials were used in this paper. The differences of molecule structures were contrasted through degree of polymerization by the detections of infrared spectrum and viscosity. The Aramid 1414 fibers were put into distilled water and seawater made by ourself respectively, then using the supersonic-wave to deal with them. After this, using the SEM to observe, found that crack appears on the fiber surfaces, presented the fibrillation and plush-like microfine fibre. Meanwhile the strength weak link increased and breaking strength and elongation at break of fibers lowered. Molecular kinetic theory was used in this paper to study loss of fibers the mechanical property.
